摘要：
The optical property of SnS2 nanocrystallites has been investigated by Raman scattering, far infrared spectrum and photo luminescence at room temperature. The Raman and far infrared spectrum of the SnS2 nanocrystallites have a shift in comparison with that of the SnS2 single crystals. The shift is mainly attributed to nanosize effect. The intralayer and interlayer force constant of SnS2 nanocrystallites have been calculated by using a linear chain model. The photoluminescence of SnS2 nanocrystallites is reported for the first time. (C) 2002 Elsevier Science B.V. All rights reserved.
